- Added normalization that translated escaped `\|` alternation to `|` outside character classes before default-mode matching.
- Refactored default matcher construction into a helper that retries compilation with malformed patterns escaped as literals after an initial failure.
- Added a regression test confirming `tools.xdev\|tools.toolbox` now returns the expected two matches in default mode.
- Rewrote logical /dev/fd operands to live OS descriptors before invoking in-process uutils.
- Added regression coverage for diff reading two process substitutions.
Fixes#5557
- Updated `run_fd_sync` to handle `io::ErrorKind::BrokenPipe` by returning exit code `141` without writing an error message.
- Added a regression test that verifies `fd` exits with `141` and empty stderr when stdout is closed early (e.g. `fd ... | head` scenario).
- Recorded the broken-pipe behavior fix in `packages/coding-agent/CHANGELOG.md`.
Added a direct-argv PTY entry point and used it for Windows launch sessions so portable-pty no longer re-quotes cmd.exe command text.
Rejected direct .bat and .cmd applications with guidance to use cmd.exe /c.
Fixes#5416
- Implemented bsd-to-gnu flag translation for `date`, `find`, `mktemp`, `sed`, and `tail` utilities to support native bsd command usage.
- Adjusted argument parsing logic in `ln` and `base32` to accommodate bsd-compatible short-flag aliases and behavior.
- Added comprehensive regression tests and bsd-specific compatibility suites across modified utilities to ensure consistent behavior.
- Updated project documentation to reflect the expanded cross-platform utility support.
- Added `rewrite_bsd_invocation` to detect macOS-style `stat -f FORMAT` syntax, preventing misinterpretation as GNU filesystem mode.
- Implemented `translate_bsd_format` to map BSD-specific format directives to GNU equivalents, including support for time forms, user/group IDs, and file metadata.
- Enabled BSD flag cluster parsing (`-LnfqF`) to allow common macOS command patterns to function correctly within the in-process `stat` utility.
- Added comprehensive unit tests to validate BSD syntax translation, sub-field handling, and error reporting for unsupported directives.
- Reflowed compile_pattern/wrapper_template comments and while-condition to rustfmt's preferred layout.
- Made wrapper_template a const fn to satisfy clippy::missing_const_for_fn under -D warnings.
A pattern like `"@types/bun": $V` parses to multiple root AST nodes and was
rejected with "Multiple AST nodes are detected". When no explicit selector is
given, retry the fragment wrapped in a minimal single-node context (JSON: `{ <frag> }`
selecting `pair`), quoting bare metavars so JSON parses. Falls back to the
original error if the wrapped form still fails, so bad patterns are unchanged.
Applies to both ast_edit (compile_pattern) and ast_grep (compile_search_patterns).
- Enabled deduplication of byte-identical edits in `apply_edits` to prevent false overlap errors.
- Added logic in `ast_edit_blocking` to filter out duplicate rewrite matches before staging.
- Updated `apply_edits` to collapse multiple identical replacements into a single deterministic operation.
- Added regression tests for both `apply_edits` and `ast_edit_blocking` to ensure identical matches resolve cleanly.
- Integrated 17 new coreutils-based shell builtins including `diff`, `date`, `ln`, `stat`, `seq`, `touch`, and others.
- Refactored vendored utilities to execute as in-process shell builtins by routing I/O, environment access, and path resolution through `pi_uutils_ctx`.
- Disabled process-level modifications (e.g., clock setting, hostname modification) to ensure safety and scope adherence within the shell environment.
- Implemented shell-specific features such as cancellation polling, custom exit code management, and efficient output streaming for all new builtins.
- Added base64, checksum utilities (md5, sha1, sha224, sha256, sha384, sha512, b2sum), path utilities (basename, dirname), and text processing tools (cut, tee, tr, paste, comm) to the shell.
- Registered new utility builtins in crates/pi-shell/src/coreutils.rs and crates/pi-shell/src/shell.rs.
- Updated Cargo.toml to include the necessary dependencies for the new core utilities.
- Vendored multiple uutils coreutils packages with custom adaptations for in-process I/O and path redirection using `pi-uutils-ctx`.
- Implemented consistent `run` entry points across all utilities to replace process-global termination and allow execution within the embedding application.
- Developed a shared `uu-checksum-common` library to centralize CLI construction, checksum computation, and digest validation logic.
- Integrated thread-local command handling and resource management to support memory-bounded stream processing and localized error reporting.
Replace mmap-backed native grep reads with bounded owned reads so concurrently rewritten files cannot fault the process or mutate captured search bytes.
Add a regression for oversized prefix snapshots and remove the direct memmap2 dependency. Fix existing pi-natives doc-markdown warnings so the native clippy gate passes.
Fixes#5205
- Removed the bash command fixup system and associated logic from both the Rust and TypeScript components.
- Deleted the redundant fixup module and its exported implementations.
- Updated technical documentation and configuration settings to reflect the removal of pre-execution bash command rewriting.
- Implemented path_depth as a tie-break mechanism for fuzzy search results.
- Updated fuzzy_find_sync sorting logic to surface shallow matches before deeper ones during score ties.
- Added a regression test confirming that root-level directories rank above nested ones when scores are identical.
- Integrated PCRE2 regex engine with automatic fallback for patterns unsupported by the standard Rust engine.
- Implemented structured JSON output, byte offset reporting, and match replacement functionality.
- Added support for advanced file traversal including Gitignore integration, decompression of archives, and path filtering.
- Updated crate dependencies to include support for expanded grep CLI options and printer utilities.
- Added support for advanced grep features including Perl-compatible regex, match limits, and byte offsets.
- Implemented robust file and directory filtering mechanisms using include/exclude patterns and custom path rules.
- Enhanced output formatting with control over group separators, null-terminated output, and binary file handling.
- Integrated `grep-pcre2` and expanded test coverage for the builtin ripgrep functionality.
- Updated gitignore loading to filter out ancestor ignore rules that match the current explicit walk root.
- Retained unrelated parent ignore rules and processed local ignore files within the root normally.
- Added a regression test to ensure ignored roots still respect nested ignore rules.
- Added `walk_depth_bound` to calculate the maximum file path depth based on glob pattern segments.
- Configured the glob walker to restrict traversal depth for non-recursive patterns, preventing unnecessary scanning of subtrees that cannot match.
- Improved response times for narrow globs over large directories by pruning the search space earlier.
- Added test cases to verify depth-bounded matching behavior and pattern edge cases.
arboard's Windows reader feeds Qt-style CF_DIBV5 payloads (BI_RGB plus
alpha mask, rewritten to BI_BITFIELDS by its header tweak) to a
header-less BMP decode that mis-places the pixel offset for V4/V5
bitfield headers, so PixPin/Snipaste screenshots failed with
ConversionFailure. read_image_from_clipboard now falls back to reading
the raw CF_DIB clipboard bytes and decoding them through the BMP file
path with an explicit bfOffBits, keeping native Windows image paste off
the PowerShell bridge.
Fixes#3426
The non-PTY bash streaming bridge queued every decoded chunk into
flume::unbounded and fired ThreadsafeFunction callbacks NonBlocking
with no budget, so a producer outrunning the JS event loop grew the
native queue (and the napi queue behind it) without bound — measured
33.5 MB queued for a 32 MiB stream with a stalled consumer, and
multi-GB RSS on longer runs. The downstream OutputSink caps sit after
the N-API boundary and cannot bound either queue.
Bound the pipeline end to end without dropping data:
- pi-natives: bridge_chunks now creates flume::bounded(64) and the
drain task (extracted as pump_chunks) awaits on_chunk.call_async per
coalesced <=64 KiB batch, so at most one batch sits in the napi
queue and the JS event loop's real consumption rate backpressures
the whole pipeline. If the JS side is gone, the pump exits and
drops the receiver so senders fail fast.
- pi-shell: emit_chunk sends with send_async().await — a full bridge
queue parks the pipe reader, which parks the child on its
stdout/stderr pipe (ordinary pipe backpressure) instead of
buffering; a disconnected receiver fails immediately so child pipes
always keep draining.
Unlike a drop-after-cap design, every byte still reaches JS: the
rolling tail view, lossless [raw output: artifact://…] capture, and
totalBytes accounting keep working for outputs past the display cap.
E2E (darwin-arm64 addon): 32 MiB through a JS callback stalling 1 ms
per call — lossless, 472 coalesced callbacks, peak RSS +21.8 MiB.
